I have an SXGA+ ThinkPad X61 Tablet nearly maxed out (L7700, 4GB of RAM, SSD) but I want to completely max this thing out so I want to upgrade it to have a fingerprint reader, what parts would I need to do that? I saw an X61 Tablet fingerprint reader on eBay and the right bezel but I understand I'd need a new LCD ribbon cable that has the fingerprint reader cable with it, can someone point me to the right cable? thanks!

You should not need a new cable; simply switch the existing screen bezel for one with an FPR should work. The socket for FPR is on the inverter card.Edit: Well, apparently that's not correct. See below.The second mPCIe slot should be a full-featured slot since some X61 configurations have a Turbo Memory card in that slot.
